Hi Python Purists!
I want all instances of a given class to share a piece of information,
but I want to set that information on the fly. I have found that this
works:
class Foo(object):
# class_variable = None # There is no real need to declare this
def __init__(self):

Cool. ;-)
Here's another, totally unrelated to counters and boards.
Kinda the opposite use of the * syntax I used earlier.
def printall(*li):
for x
I like this.
class Counter:
def __init__(self):
self.score = 0
def incr(x, y):
self.score += 2*x+3*y
class Board:
def __init__(self):
self.counter = Counter()
self.curcoords = (0,0)
def update(self)
self.counter.incr(*self.curcoords)
Whatever OOP term is used to d

Hi,
I'll try to swallow down the "Globals are eevil" comment, there's enough
literature on that already.
Maybe I'm spoiled from programming too much Java in the last year, but
IMHO it's a good idea to put the singleton instance into the class
itself rather than into some module.
This way, you (c

Hi Python Practicioners!
I'm trying to come to terms with how Python handles the scope of
objects. In particular, I'd like to create an instance of one class and
make it available inside instances of other classes. Something like:
# Test 1-
# I want a "globa
